Application areas
It is applied in aquatic biology and marine biology, intertidal ecology, coral research, lake ecology and other fields.In situ measurement of corals,
The only instrument for the physiological activity of large seaweeds and submerged plants.It can also be used to measure the photosynthetic activity of terrestrial higher plants in the rainy season.Microalgae can be measured, but is not very suitable for phytoplankton measurements in natural water bodies.
